Cheryl, our 8 week old Dutch Shepherd is overly aggressive with my 10 year old son. He cannot even play with her without being attacked and bitten. I chalked this up to puppy play, but he is becoming upset about it. Someone suggested that he use a water bottle to spray her during these aggressive episodes. I don't want her to dislike him though. Is this something that we should consider? Eventually she will go to obedience school but what can we do in the interim?
